SPECIFICATION forming part of Letters Patent No. 31%,997, dated April 7,1885.

Application filed August 15, 1883.

To all whom it may concern:

Be it known that I, CHARLES B. CAMP, of Sturgis, in the county of St.Joseph and State of Michigan, have invented certain new and usefulImprovements in Cots and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. I

My invention relates to an improvement in canvas-covered cots, the frameof which is composed of jointed sections adapted to be folded together,the object of the same being to provide a cot of this class which shallbe strongly I 5 constructed and firmly braced, and which can with greatfacility be set up for use or folded into a compact and easily-handledpackage which may be stowed away in a small space.

With these ends in View my invention consists in certain novel detailsin the construction and arrangement of the several parts, as will bemore fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of thecot-frame with the canvas removed. Fig. 2 is a similar view of acompleted cot. Fig. 3 shows the cot when folded. Fig. 4 is a detachedview of the center hinge, and Fig. 5 is a view of the hinges 3O employedfor securing thehead-rest to the side pieces of the frame.

The side rails Aare each made of two sections,a a, the adjacent ends'ofwhich are pivotally secured to the upper ends of the cen- 5 tral legs,12, through the intervention of the hinges B. These hinges B-one on eachside of the frame-are preferably made of cast-iron, and consist of twoseparate plates, one of which is provided with studs for securing thecot- 40 frame thereto, while the other simply acts as a locking-plate.The main or central studs, 0, are preferably formed integral with theportions B of the hinges, and are adapted to be passed through the upperends of the legs 5 b below the side rails A. These hinges are preventedfrom turning on the legs a by the side flanges, D, and flanges D, which,combined, closely embrace, respectively, the opposite side edges and theupper ends of the legs, and 0 consequently hold the hinges and legs inthe same relative positions. The flanges D of (No model.)

each hinge are shaped as shown in Fig. 4, and

curved concentrically to the studs E, which latter are situated neartheopposite side edges of the portion B, near the upper end thereof. Thesestuds are passed, respectively, through the adjacent ends of the.sections a a of the side rails, and form bearings therefor,while theinner ends ofthe said sections a a are curved to conform to thecurvature of the flange D. The outer ends of the studs 0 and E areconsiderably reduced in size, and are adapted to fit in correspondingopenings formed in the plate B of the hinge B. After the studs of theplate have been passed through the legs 5 and side rails of the framefrom the outside the reduced ends of thestuds projectinwardly beyond thelegs and rails, and the plate B is placed thereon. The reduced ends arethen upset, or nuts can be screwed thereon and seenrely hold the partsin position.

The central legs, b b, are connected together near their upper ends bythe cross-bar e, and near their lower ends by the cross-bar f. The

,side rails Aare also connected together near 7 the outer ends by thecross-barsg, to which. the end legs, 72, are pivotally secured. Theselegs, when the cot is open, incline outwardly, so as to form a solidsupport, and the legs at each end of the cot are connected together by as cross-bar, t, which, besides preventing the legs from spreading apart,also serves as a means for attaching the outer ends of the brace-rods kto the central legs, b. The inner ends of the rods 70 are pivotallysecured to the cross-bar f 3 of the legs b, and limit the outwardmovement of the end legs.

From the foregoing it will be seen that by folding up the sections a ofthe side rails until they stand in a vertical position over or in linewith the central legs, I), the end legs, h, are also turned inwardlyalongside of the said sections a a until they also restin a verticalposition. By moving the sections a a to a horizontal position the bracesit turn the end 9 5 legs, 71, outwardly simultaneously with the movementof the sections a a.

The upper sections, a, of the cot-frame are slightly shorter than thesections a, and are connected at their outer ends to the side rails m ofthe head-rest F. These side rails m are connected together near theirouter ends by the cross-harm, and the whole is pivotally secured to theside rails of the cot by the hinges G. These hinges G are composed oftwo plates, similar to the hinges B, one of said plates being providedwith three lugs for securing the parts together, Two of thelugs of eachhinge are adapted to be passed through the end of the section a for thepurpose of rigidly holding the hinge thereto, while the other lug passesthrough the inner end of one of the side pieces m, and forms a pivotalbearing therefor. The upper ends of the side rails m of the head-restadjacent to the sections a are curved sufficiently to enable the saidhead-rest to be inclined to suit the user, while the extreme inner endsof the side rails m are squared and adapted to abut against the adjacentends of the side rails of the cot for the purpose of preventing therails m from sinking below ahorizontal or any predetermined position.

H are spiral or other suitable springs situated on opposite sides of thecot,and connecting the side rails m, near their outer ends, to thesections a, for the purpose of holding the head-rest elevated, andenabling it to yield under the weight of the person using the cot.

I are books pivoted to the sections a, and adapted to engage staplessecured to the sections at, for the purpose of locking the parts whenthe cot is folded.

The edges of the canvas 0 are secured to the side rails of the frame,and the upper end thereof is firmly secured to the pillow 0, through theouter edge of which the cross-bar in passes. This pillow is stuffed withhair, excelsior, or other suitable material, and rests between the sidebars m, so as to enable it to give or yield to accommodate itself to thehead of the user and form a comfortable rest.

In preparing this cot for use it is simply necessary to stand it in avertical position, with the legs 6 resting on the floor, withdraw thehooks from the staples and slightly separate the sections a a, whichwill cause the said sections to assume a horizontal position and thelegs their proper relative positions thereto, as before described,without the necessity of a separate adjustment for any of the parts.

This device is exceedingly simple in construction, is durable in use,and can be manufactured and sold at a small, initial cost.

It is evident that slight changes in the construction and relativearrangement of the several parts might be resorted to without departingfrom the spirit of my invention, and hence I would have it understoodthat I do not confine myself to the exact construction shown anddescribed, but consider myself at liberty to make such changes as fairlyfall within the spirit and scope of my invention.

I am aware that it is not new to secure a yielding head-rest to anon-folding bedstead, and hence I make no claim thereto; but, Havingfully described my invention, what I claim as new, and desire to secureby Letters Patent, is-

'1. In a folding cot, the combination, with the sectional side rails, ofthe bars m, forming continuations of said side rails, the hinges forsecuring the side rails and side bars together, and the springsconnected at their opposite ends to the side rails and side bars, all ofthe above parts combined as described.

2. The combination, with the side rails, A, short rails to, the sidebars m, hinged to the outer ends of the short rails, and springs foryieldingly holding the side bars in an elevated position, of the legs I)and h, cross-bars f and i, and brace-rods connecting the end cross-barwith the central cross-bar.

3. The combination, with the side rails and legs constructed andarranged substantially as described, of the hinges B, connecting theside rails and central legs, and consisting of an inner plate providedwith curved bearings for the ends of the rails, and with studs, and anouter plate provided with openings registering with the studs, all ofthe above parts combined as described. 4. In a folding cot, thecombination, with side rails and a flexible covering secured thereto, ofyielding sidebars pivotally secured to the ends of the side rails, across-bar connecting the outer ends of the side bars, a pillow securedto said cross-bar and to the fiexi ble covering and resting between theside bars, substantially as and for the purpose described. In testimonywhereof I have signed this specification in the presence of twosubscribing witnesses.
